crypto: khazad,wp512 - remove leading spaces before tabs

There are a few leading spaces before tabs and remove it by running the
following commard:

	$ find . -name '*.c' | xargs sed -r -i 's/^[ ]+\t/\t/'

At the same time, fix two warning by running checkpatch.pl:
	WARNING: suspect code indent for conditional statements (16, 16)
	WARNING: braces {} are not necessary for single statement blocks
